Our HIGHLY SCENTED hand-poured candles are crafted using 100% soy wax. Soy is a clean burning wax with a long burn time. Soy is also a renewable resource and completely biodegradable. Since soy is made from hydrogenated soybean oil, the jar cleans up with soap and water and can be reused. Purchasing soybean products creates important economic growth for the agricultural sector of the US economy.
